HOWTO/manpage: update percentage explanation using '%'

82dbb8cb (HOWTO: add offset unit info for offset= option) added
how to specify offset= option in percentage format based on below post,
which was technically correct, but str_to_decimal() invoked via
option parser can convert '%' format to low-level representation.

This commit replaces 82dbb8cb using '%' syntax since this is
considered better for documentation. Note that size= option which
also supports percentage uses '%' in documentation.

in what units is offset option?
